Embodiment Construction

[0023] The technical solutions of the embodiments of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] In the NGN network, after the H.248.64 protocol introduces the concept of the media gateway working in routing mode, all incoming IP packets flowing through the media gateway pass through one or more interfaces, and multiple packet filtering rule information must be set on the interface to achieve Filter incoming packets to achieve the purpose of communication security. In order to meet the requirement of applying multiple pieces of packet filtering rule information on a single interface of the media gateway to filter incoming packets, a packet filtering rule table (filter table) on the interface can be maintained on the media gateway, and the packet filtering rule table can include one or A plurality of packet filtering rule entries, and each packet filtering rule entry includes a packet fil...

Abstract

The embodiment of the invention provides a method, a system, a media gateway and a media gateway controller for processing packet filtering rules. The method comprises the steps of: receiving a control message for instructing the media gateway to operate the packet filtering rules by a receiving pocket, and processing pocket filtering rule table items in a pocket filtering rule table according to the control message. In the embodiment of the invention, the media grate can flexibly add, modify, delete and carry out audit on all pocket filtering rule table items in the pocket filtering rule table according to the updating or audit instructions of the media gateway controller to guarantee the uniformity of the pocket filtering rules stored in the media gateway and the media gateway controller, ensure the media gateway to filter inflowing pockets safely and improve the data transmission quality.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular to a method and system for processing packet filtering rules, a media gateway, and a media gateway controller. Background technique [0002] With the rapid development of computer and communication technologies, it has become the direction of network development to carry multiple services such as voice, data, and images through public packet networks. Under such service-driven and network convergence trends, a next generation network (Next Generation Network; NGN for short) with a softswitch device as its core emerges as the times require. NGN is implemented in the packet network and adopts a distributed network structure, which can effectively carry voice, video and multimedia services, and realize the separation of service application, service control and service transmission functions. figure 1 It is a schematic diagram of the existing NGN ne...
